4. A video sequence is given to be encoded using H.263 in PB-mode, having a frame size of QCIF, frame rate of 30 fps, and video length of 120 minutes. The following is known about the compression parameters: on average, four l-frames are encoded per second. The video at the required quality has an l-frame average compression ratio of 8:1, an average P-frame compression ratio twice as good as l-frame, and an average B-frame compression ratio twice as good as P-frame. Assuming the compression parameters include all necessary headers, calculate the encoded video size. (Assume images are 8-bit long)
